The invention has for an object the construction of an article asmentioned which is char- Vv acterized by a seat and extension with ahinged back arranged to maintain a raised or a lowered position, andmechanism for extending the seat.

extension to provide suflicient length so that the chair may be used asa bed.

Still further the invention proposes an arrangement whereby a catch isadapted for 'holding the back in an upright position'and releasable toallow the back to be moved to the horizontal position.

Furthermore the invention also proposes the provision of means forholding the back ina substantially horizontal position when lowered.

' As'another object of this inventionit is proposed to arrange acarriage beneath' the seat supporting .the seat extension' piece adaptedto be raised to a suitable height'when the carriage is extended so as toadd to the length of the device.

Still further the invention proposes the construction of an article asmentioned which is simple and durable and whichimay be manufactured andsold at a reasonable'cost.

For vfurther comprehension of the invention, and of the objects 'andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features `of the invention are more particularly setyforth.

position level with the seat 10 and so extend the size of the bed. Thecarriage 26 comprises four vertical wallssimulating the sides of a boxjoined by several longitudinal members 28 at the bottom and at the top.A means is provided for extending the carriage and comprisesv a `springof several leaves 29 acting against the rear wall of the carriage and atransverse bar 30 between the side walls 11, The carriage 26 is providedat the sides with wall extensions 32. Several rollers 3,3 are arrangedupon the outer faces of the wall extensions 32 and on the side walls ofthe carriage and work in tracks 34 mounted upon the inner faces of theWalls 1l. Several rollers 35 are mounted on the carriage 26 and restupon the Vground The carriage 26 is shown in its retractedVposim tion inFig. 1. It should be noticed that in this gure all of the rollers 33engage the tracks 34. When the carriage is extended, necessarily therollers 3 3 upon the front of the carriage will extend out from thewtracks, I but the rear-rollers v33 inLCQIliULI-.lilon with `the-rollers3-5 are depended upon to slidably guidethe carriage Sothat'itmay easily -be moved inwards.

The seat frontextension piece 27 preferably shouldbe angupholsteredmember mounted withina Aframe i317. This frame 37 has severallongitudinal members 38 along its bottom.

These bolts0 ,areadapted to engageagainst the too Hauses 28 upon the carriage.

level of the seat 10 and comprises several leaf springs 4l Vsupportedupon standards 42 project-` ing kfrom .the members 28 of the carriage.`26,. Thesesprings .41 engage against the undersides of .certain of `theflanges 438 and tend 'to normally urge the frame 37 upwards. The frameis restrained'from rising by a rod 43 which sattached upon the centerfiange38 and which engages intol a .tubular member 44 mounted upon thebottom ilange 281.of the carriage 26. A helical spring .41-l is mountedupon thetubularmember 44. and acts between a flange at the base ofthetubularmember and a'flange upon the upper end of the rod 43fforthepurpose of supplementing the .action of the springs 41 in liftingthe seat extension piece 27. A lockrod 45 passes through the member 28and .engages a cutout 'in the rod 143 so as tohold the rod in loweredposition. The lock rod 45`is urged into locking position by a spring 46which isattachedat one end upon Va lug .45 of the Vlock rodand at theother end on the carriage 426i Al cross piece 47 is mounted upon `Ythelug 45 and extends from the sides of the 'carriage 26 and is adapted tostrike against stationary stop mem.- bers .48 Afixed upon the sidesofthe walls 1110- cated so as to cause the releasing ofthe rod 243 whenthe carriage is in itsfully extended position.

A means is provided for holding 'the carriage 26 Vretracted andcomprisesa hook 49 fixed on a rodl49-"supported onthe side walls llandengageablein an opening 28 of one of the members 28. Springs 57 on theYrod 49' act between the rod 49 and the walls l1 for normally urging thehook 49V into vlatching position.` The hook 49 has a rear cam shapedprojection 49.LL on its rear end adapted to be engaged upon the hook-16for the purpose of-pivoting the hook 49 to ldisengage `it from itslatching position. i v

A mechanism is also provided for latching the seat back 12 in itslowered position. This mechanism comprises a rod 50 having a bolt 51lixed at its top end and working in a slot 18 in the rodv-will--be-1.-1rgeo1 inwards by an arcuate shape on the t,op ,of theharand then outwards 'as illustrated by the dot and dash lines in Fig. 9,to assume apo'sition-ove-r the top of the bar 53 and so latch theseatback in the horizontal position.

These bolts Vl61 are soldered, riveted,'or'welded to the flanges 38 so as to act in unison with theeilanges.

The mechanism mentioned at the latter portion of Vthe previous paragraphcomprises a nger- 66 engaging each ofthe slide bars 60 and projectingfrom a transverse'shaft '67 swiveled in the'sides .of the carriage 26;Another finger 68 projects from the shaft 67 and connects with avertical vrod 69 terminating at 'the bottom endv 60 and so free thebolts 61. vThe slide bars 60f are of `channel shape, see Fig. 7 and theopenings yforooactionwith the openings 63 are formed in the base ofthese channel shapes.

` The operation of the device may bepsummarized as follows: Assume it tobe in-the position The slide 71 may be pulled .K Any arrangement may beused forl slidably Supporting the slide -bars 60 in positionforexamplebrackets illustrated in full linesin Fig. 1`. 'The'device' maynow be used as a chair. To convert it? into `ay bed it is necessary thatonesY fingers be engaged through the opening 20 and move'the head 19 androd 18 upwards..v This causes the release' of the keepers so that theback 12 may be pivoteduto the horizontal position." YDuring the 'mo tionof the seat backf12 to thehorizontal'p'osi tionvthe hook '-16 willstrike the cam end 49n of the hook 49V topivot the hook v49 out of itslatching position. This releases the carriage 26 which is immediatelyurged outwards by the spring 29. When the carriage has substantiallyreached its fully extended position the cross piece 47 will strike thestop members 48 to arrest the motion of the lug 45 while the carriageitself may move slightly further outwards until arrested by compressionof the spring 46. 'I'he relative rearward motion of the lug 45 moves therod 45 so that it disengages from the rod 43 releasing the seatextension piece 27 which is then immediately raised by the springs 41and 41.

The nuts 40 will strike certain of the flangesy 28, see Fig. 11, tolimit the upward motion of the extension 27. Simultaneously the cutoutp0rtions of the rods 6l Will be aligned with the openings in the channelshaped slides 60 so that the springs 64 may move within the channelshaped slides 60 to latch the seat extension in the raised position. Thedevice may now be used as a bed.

The device may be converted to the chair, by rst raising the seat back12 from the horizontal to the vertical condition. As this seat back israised the hook 16 will strike the cam 49a and idle past without anyeffect, except momentarily pivoting of the hook 49 which is thenimmediately returned by the springs 57. Next the slide 71 should bemoved outwards and stepped upon to cause downward motion of the rods 69and pivoting of the finger 68, turning of the shaft 67, and moving thelingers 66 and the channel shaped slide bars 66 into positions in whichthe bolts 61 are free. Then the seat front piece 27 should be depressedmanually until the rod 43 is completely extended in the tubular member44. Next the carriage 26 should be moved inwards and this automaticallycauses the transverse rod 47 to leave the stops 48 so that the spring 46may move the catch rod 45 to latch the rod 43 in the lowered position.Thus the carriage 26 is now latched in its lowered position. Thecarriage 26 must be moved completely inwards against the action of thespring 29 until the hook 49 engages the opening in the member 28 andholds the carriage in the retracted position.
